7.4.1 Inputs

The TLV703x and TLV704x input common-mode extends from VEE to 100 mV above VCC. The differential input voltage (VID) can be any voltage within these limits. No phase inversion of the comparator output occurs when the input pins exceed VCC and VEE.

The input of TLV703x and TLV704x is fault tolerant. It maintains the same high input impedance when VCC is unpowered or ramping up. The input can be safely driven up to the specified maximum voltage (7 V) with VCC = 0 V or any value up to the maximum specified. The VCC is isolated from the input such that it maintains its value even when a higher voltage is applied to the input.

The input bias current is typically 1 pA for input voltages between VCC and VEE. The comparator inputs are protected from voltages below VEE by internal diodes connected to VEE. As the input voltage goes under VEE, the protection diodes become forward biased and begin to conduct causing the input bias current to increase exponentially. Input bias current typically doubles every 10°C temperature increases.
